1. Product Description
Layout of system
The DELTABOOSTER is a flexible pump station capable of supplying several simultaneous
users with pressurized cold / hot water through a pipeline. The DELTABOOSTER has been
pre-adjusted for a certain line pressure which is also the maximum working pressure.
For the DELTABOOSTER a system of nine different spray lances has been developed. From
a diagram the user can choose the lance giving the exact pressure and water volume required
for his cleaning job.
As standard the DELTABOOSTER system is available with capacities from 2 - 6 users and
pre-adjusted at a line pressure of 160 bar (other pressures are available according to wishes
of the customer).
A plant with a capacity for 3 users can be upgraded to 4, 5, or 6 users at any time, and more
DELTABOOSTER plants can be connected up on the same pipeline.
With the DELTABOOSTER users no longer have to bother about the pros and cons of high
or low pressure. From now on all choices are united in one system, and the solution with the
optimal effect on the job to be done may always be found.
In more technical terms the plant operates in the following way:
Water from a COLD and a HOT connecting valve is mixed in a water tank of the type A airgap.
From here water of the required temperature is drawn into the high pressure pumps of the
DELTABOOSTER which pressurize the water and supply it to a pipeline.
When one or more outlet points are being used, the number of pumps required to maintain the
pressure will automatically start up.
When the cleaning stops successively, one of the excess pumps will cease operation each 15
sec. If all cleaning is stopped then controls will ensure that the requisite pressure for re-starting
is maintained. If a leakage is caused to the pipe system then the pump station will be totally
switched off after some 2 minutes. In the case of an internal hose leakage in the system, faulty
water supplies, excess temperature of inlet water, excess motor temperature or excess power
consumption the system will be switched off.
When starting and stopping the individual pumps, controls will ensure an even distribution of
operation time on the pumps by switching between all the pumps in the system.

1.1 Model survey and main functions
The DELTABOOSTER comprises 4 different modules:
1.
2.
3.
4.
A switchboard
A water tank
KEW Technology C3K pumps
Cabinet / frame
The DELTABOOSTER is made of stainless materials through and through.
DELTABOOSTER switchboard
The switchboard comprises:
- main (emergency) switch, to which the supply cable is connected
- control switch 24V AC
- push-button switch for starting up
- maximum current breaker (short circuit and overload) for each pump
- contactors for connection of 3 or 6 pumps.
The switchboard also incorporates an electronic control that monitors the operation of the
system; i.e. a) selection at any time of required pump capacity; b) even distribution of load on
individual pumps; c) mixing of desired temperature of water drawn from a cold water and a
hot water supply and d) the indication of status/fault on a control panel.
It also incorporates hour meters to show hours of operation of each individual pump.
The switchboard has been prepared for
connection of 6-pumps: (4, 5, and 6 pump plants)
or for connection of 3-pumps: (2 and 3 pump plants)
The switchboard which on delivery controls 3 pumps may later be expanded to control
6-pumps.
The DELTABOOSTER is available for the following voltages:
3 x 230V
3 x 346-400V,

Water tank
The water tank of the DELTABOOSTER has been constructed in accordance with BS 6281
part 1 (type A air gap). As standard the water tank is mounted for water connection in the left
side (seen from in front) but the water tank is also available with prepared water connection in
the right side.
The water tank of the DELTABOOSTER incorporates the following:
- two solenoid valves for water inlet, cold and hot water respectively
- various control valves
- temperature sensor and level switches in the float tank
- overflow
- connection of up to 6 pumps
- filters in in-lets
C3K pumps
The C3K pumps are designed for the very demanding environments in which they are used.Their
durability has been achieved by the use of ceramic pistons *) and valves of stainless steel.
Each of the pumps are connected by individual non-return valves to a central manifold. Thus it
is ensured that a defective pump will not cause a malfunction or an unintentional by-pass situ-
ation.
*) The C in the pump designation C3K stands for "Ceramic".

1.2 Selection of system
The great degree of flexibility, an important characteristic of the DELTABOOSTER, means that
each individual customer may select the system which suits his cleaning needs.
The following solutions are offered:
NUMBER OF PUMPS
Choose from 2 to 6 pumps depending on the capacity required at the same time. In other words,
the number of pumps should be decided on the basis of the number of places that are to use
the system at one and the same time.
LINE PRESSURE
The line pressure is the maximum working pressure for the individual user and is of importance
to the dimensioning of the pipeline, of course.
As a standard the system is adjusted to a line pressure of either 120 bar or 160 bar, but it may
be adjusted to a line pressure within the area 90 to 160 bar. This adjustment should only be
done by a specialized Nilfisk-ALTO customer engineer.
SELECTION OF SPRAY LANCE
For each of the line pressures (120 and 160 bar) there are nine different spray lances developed
especially for the DELTABOOSTER. Each of the nine spray lances represents a combination
of pressure and water volume. Users may therefore always select the job-right combination of
pressure and water volume.

1.4 Location of the DELTABOOSTER
The DELTABOOSTER is fitted with vibration absorbing rubber supports, so it may be placed
straight on an even surface (see section 2.2).
The plant must be placed in frost-free premises where the maximum temperature does not
exceed 40°C.

1.5 Installation requirements for water connection
The water tank is fitted with two water inlets, one for cold water (BLUE marking) and one for hot
water (RED marking).This allows the operator to control the temperature of the water being used.
If no temperature control is desired both water inlets may be attached to the cold pipeline.
At least 1 cold water inlet should always be connected and the hot inlet water should never
exceed 80°C.
Each pipeline should be capable of supplying the system with at least the water volume that
answers to the capacity of the system ( no. of pumps - l/min, cf. 1.3.3) and at min. 2 bar. The
water pressure must not exceed 10 bar. If water is being drawn from the lines at other points,
the line capacity should be equally bigger.
In order to achieve optimal temperature control the shut-off valves on both the hot and the cold
pipeline should be adjusted so that the water volume of each line comes as close to the required
water volume as possible.
Water should be connected at the inlet sockets with two 1" flexible hose connections (included
in the MK-Mountig Kit).The two water inlet hoses are 1 m long and fitted with a 1" external taper
pipe thread. Shut-off valves should be fitted right next to the connections on the supply lines, but
no extra non-return valve is required as the system is fitted with an airgap type water tank.
If the water holds running sand or other impurities external filters should be fitted in addition to
the internal filters.
The high-pressure connection to the pipe system should be by means of the 3/4" high-pressure
hose supplied with the system. The hose is fitted with an Ø22 plain branch for connecting to
cutting ring hose connection.

1.6 Installation requirements for mains power connection
The power system of the DELTABOOSTER is designed in conformity with the common Euro-
pean standard:
EN 60204-1 (October 1992): Electrical equipment of machines, Part 1: General requirements.
Powershouldbeconnectedthroughaflexiblerubbercableholdingcopperconductorsfor3phases
and earth (PE).The minimum dimensions of the cable are determined by the power consumption
of the current system (cf. data sheet), but common to all systems is the following:
Max pre-fuse:
125 A
Max core section of cable:
35 mm
In consideration of a future extension of the plant we recommend you to use a cable with a min.
core section of cable of 25 mm.
Earth wire protection is required and the connection of the DELTABOOSTER to the mains power
supply MUST be carried out by an authorized electrician in conformity with local regulations.
To ensure maximum protection of persons, the installation should be protected by a Residual
Current Device (RCD).

1.7 Pipe system
1.7.1 Location of pipelines/general instructions
-
Thepumpstationandoutletpointsshouldbeplacedsothatthelinesbecomeasshortas
possible.
-
-
The line should be arranged with as few bends as possible.
Sometimes it may pay to split the line close to the pump station so the lengths conducting
large volumes of water become as short as possible. A centre location of the pump station
in relation to the outlet points would also lead to smaller pipe dimensions.
Pipe lines should be placed on walls of tile or concrete, otherwise great care should be taken
(reinforcement plates etc.)
-
-
-
Pipe lines should be placed so that damage is prevented (collision, frost, extreme attacks of
corrosion, etc.)
Pipelinesshouldbefittedinavisuallocationeverywhereorsothattheymayeasilybe
inspected. Lines should not be incorporated in walls or floors. When leading through walls
be careful not to enclosed. (Special lead-in bushes are available)
The outlet points should be placed as close to the operation point as possible and so that a
hose length preferably of 20 m is used.
-
1.7.2 Types of pipes - standards
Seamless pipes of precision steel are used for the pipe system according to DIN 2391/C of St.
35.4 material quality, normalized, bright annealed and electro galvanized
or welded steel pipes, stainless, calibrated and glowed according to DIN 2463 - 1.401 d3-- (DIN
17457 cl. 1).
Alternatively,seamlesspipesofprecisionsteelindimensionsaccordingtoDIN2391andstainless
material quality e.g. Werkstoff no. 1.4301, 1.4436 or 1.4571. Comparable qualities to Swedish
standards are SIS 2333 or SIS 2343.
Pipe dimensions:
The following sizes are used with electro galvanized precision steel pipes:
- ∅15x2
- ∅22x2.5
- ∅30x4
The following sizes are used with stainless precision steel pipes:
- ∅15x1.5
- ∅22x2
- ∅30x3
In connection with branches close to the pump station it should be possible to avoid the ∅30
dimension for most 44C3 systems. For 160 bar systems fittings with a permissible working pres-
sure of min. ND 160 bar are to be used.
Please note that the pipe dimension ∅30 according to DIN 2353 is used together with a stronger
type of fitting (S-series) and pipe systems with this dimension therefore become more expensive
than e.g. an ∅22 line - particularly in multi-pump systems.

1.7.4 Dimensioning of pipe systems
The below diagram shows the current pressure drop graphs meant for the dimensioning
of pipe systems used in connection with the DELTABOOSTER plant.
The diagram illustrates two vertical divisions for
II) electro galvanized steel pipes 15x2 mm
-
22x2.5 mm - 30x4 mm
30x3 mm
I) stainless steel pipes 15x1.5 mm - 22x2 mm
-
The pressure drop per metre of pipe at a given water volume may be read from the fol-
lowing pressure drop graph.
Water volume [l/min]
When dimensioning the system be careful that the maximum pressure drop at the remotest
outlet point does not exceed 15 bar at full load.
The pressure drop in elbows and branches is of minor importance in relation to the pressure
drop in the pipes.

Two different conditions may be used when
dimensioning the pipe system:
A. Based upon a fixed type of spray lance (capacity l/min)
B. Based upon max. capacity, i.e. all spray lances may be used anywhere
A:
If standard lances (17 l/min) are selected for outlet points a, b and c the maximum load on line
b-c = 17 l/min.
PRESSURE
According to the diagram the use of a 50 m ∅15 mm
pipe will result in a pressure drop of:
DROP
2.3 bar
In the diagram you follow the 50 m division vertically
upwards to the curve symbolizing 17 l/min through an
∅15 mm pipe. From here proceed horizontally and a
pressure drop of 2.3 bar is had.
Maximum load on pipe line a-b = 35 l/min.
Use of 40 m Ø15 mm pipe will result in a pressure drop of:
7.4 bar
Maximum load on pipe line M-a = 51 l/min.
Use of 70 m Ø22 mm pipe will result in a pressure drop of:
Total pressure drop
3.3 bar
13.0 bar
The aggregate pressure drop on the three lines is less than 15 bar and the dimension requirements have therefore
been met.

Maximum load on line a-b = 50 l/min.
Use of 40 m ∅22 mm pipe will result in a pressure drop of:
2.0 bar
Maximum load on line M-a = 50 l/min.
Use of 70 m ∅22 mm pipe will result in a pressure drop of:
3.2 bar
Total pressure drop
14.5 bar
The aggregate pressure drop on the three lines is less than 15 bar and the dimension require-
ments have therefore been met.

This means that ∅22 mm pipe is to be used from the pumps to outlet points b1 and b2 and
∅15 mm for the rest.
The examples show different ways of installing the pipe system.What to prefer in each individual
case highly depends on the building where it is to be located and special requirements, if any.
Due regard should be paid to the fact that big pipe dimensions and units are considerably more
expensive, and the financial costs of each solution should therefore always be compared to
one another.

1.7.6 Mounting requirements and hints
Temperature compensation
When hot water (max. 75°C) is used in the system due regard should be paid to thermal expan-
sion of the pipes when mounting the system. When raising the temperature from10°C to 75°C
the system will expand some 0.7 mm/m. In order to allow for this expansion long straight lines
should be fitted with compensators in the form of U-bends or hose connections.The pipe system
should not be fixed too close to any corners and close to Tee connectors at outlet points.
U-bends/hose connections
At a max. temperature on the system of 75°C a compensator should be fitted at 20 m intervals
if there are no elbows on the line. If the pipe may expand at one end compensators may be left
out if the pipe is not fixed at the Tee connectors at the same time. Compensation for ∅15 and
∅22 should be in the form of hose connections or as U-bends on the pipe. Use hose connec-
tions for ∅30.

FIXATION AT CORNERS AND TEE CONNECTORS
Standard distance between pipe brackets is some 2 m.
MOUNTING OF PIPE LINES/GENERAL INSTRUCTIONS
-
-
Shorten the pipes by sawing off and take off burrs.
When bending the pipe bending radii should not be smaller than those stated in the chart
under “U-bends/hose connections” and the bending should always be completed in a bend-
ing tool with rolling matrixes in order to prevent deformation of the pipe.
Union nut and cutting ring should be greased with oil and the cutting ring should be pre-fitted
to the pipe in the screw joint or the annealed pre-mounting socket before fitting the pipe.
Place the pipe brackets at a maximum interval of 2 m.
Use ∅6 hexagon-headed screw with expansion joint for wall or concrete walls when
mounting wall fittings, alternatively use a knock-type anchor for concrete walls, e.g. HILTI
type HPS 8/30.
-
-
-
-
In systems meant for hot water, care should be taken to place the pipe brackets on a straight
line in order to prevent the lengthwise expansion of the pipe.

1.9 Multipressure spray lance system
Spray lances with colour coding are used as standard equipment.The colour code indicates the
water volume and pressure supplied by the specific lance.
The different water volumes and pressures depend on the high-pressure nozzle, pre-nozzle
and spray lance fitted.
The spray lances for 120 and 160 bar respectively differ in that the spray lances for 120 bar
are fitted with a GREY nozzle protection, whereas the spray lances for 160 bar are fitted with
a BLACK nozzle protection.
Multipressure spray lances are available in 3 different lengths: 50 mm - 570 mm - 930 mm.

2.4 Mains power connection between the DELTABOOSTER
and the supply network (cf. Fig. 5)
All measurements and connections described below should be carried
out by authorized specialists !
1) The DELTABOOSTER should be connected to a three-phase mains supply at the rated
voltage, cf. the model plate. Max. 125 Amp pre-fuses.
2) Theconnectionshouldbeestablishedthroughaflexiblerubber cablewith3phasecores
and one earth conductor to be led through the sealing connection (2) and into the bottom of
the switchboard through the open angle flange (3).The angle flange is opened by loosening
two nuts. The cable should be connected direct at the main switch S1 and the main earth
terminal (4). When the cable has been properly mounted in the main switch S1, the angle
flange should be closed around the sealing connection (2) and the cable placed in the two
cable reliefs (1).
The cable should be rated to the existing current consumption which has been stamped on
the DELTABOOSTER model plate. It is advisable to apply a cable with a conductor cross
section of minimum 25 in preparation for a later expansion.
3) It is also advisable to take additional precautionary measures to protect the user by installing
a Residual Current Device (RCD) / Ground fault circuit interruptor (GFCI) in the DELTA-
BOOSTER supply line.
4) Finally, check that fuses F1 - F2 and F3 (cf. wiring diagram) have been mounted in the re-
tainers and that the overload cut-out Q1-Q? has been connected and set correctly (cf. C3K
model plate).
5) With an appropriate measuring equipment the connection of earth cables from the outlet of
the fixed installation to a metallic part on the high pressure outlet of the machine should be
checked. The phase conductors of the supply cable should be subjected to a high voltage
test with the main switch in off position.
At Nilfisk-ALTO the DELTABOOSTER has been tested on the above-mentioned items as a
separate machine.
6) The door to the switchboard should be closed and locked.The system is now ready for run-
ning in and function testing.

2.5 Starting up/running in
Prior to starting up the customer engineer should be fully confident with sections 3.4 - 3.6 of
the Operation Manual describing the instrument panel, settings and starting up/operation.
If any faults appear during the starting up and running in, sect. 3.10 on trouble-shooting may
help you.
2.5.1 Oil control

will light up.
In the case of repeated low oil level (oil waste) please contact a Nilfisk-ALTO service
technician.
2.5.2 Start
Turn the main switch to position - I -.
Turn the operation switch to position - I -.
The water tank will now be filled up. Press the starting switch when the system has been made
ready for venting of the pumps.
2.5.3 Venting of pumps
Venting should be carried out on each pump individually (cf. sect. 3.5.2) as power is only con-
nected to the water tank module and the relevant pump during the venting process.
The pump should be vented in the following way:
1. Make sure that only the pump to be vented is switched on (cf. Fig. 3.5.2).
2. Open the cabinet.
3. Loosen the venting screw of the pump (cf. Fig. 7).
4. Fit a hose to the end of the venting screw and lead it to waste (jar or the like).
5. Start the pump and let it run until all the air has been removed.
6. Tighten the venting screw.
7. Repeat the procedure until all pumps of the DELTABOOSTER have been vented.
Fig. 7

2.5.4 Venting of pipe system
When each pump has been vented the system is started up, and all high- pressure cocks on
the pipeline are opened one at a time until all air has been removed. Begin with the remotest
high pressure cock.
Please note that the cock should be closed for a short time before opening it again.The latter is
done in order to prevent the leakage stop from being activated when venting long pipelines.
2.5.5 Adjustment of line pressure
Adjustment of line pressure should only be carried out by an
authorized Nilfisk-ALTO service technician.
As a standard the DELTABOOSTER is adjusted to a line pressure of 160 bar, but it may be
adjusted to any line pressure within the area 90 to 160 bar.
It will always be expedient to choose a line pressure corresponding to the highest working pres-
sure / nozzle pressure which you know will be required for your cleaning jobs.
A Nilfisk-ALTO service technician can adjust the high pressure switch (1) and the overflow valve
(2) to the required line pressure. The pressure can be read from the pressure gauge (3).

How to use the DELTABOOSTER
Users are urgently requested to study these instructions before operating the DELTABOOSTER.
The individual user is personally responsible for handling and using the cleaning system properly and
safely. It is therefore urgent that all users are instructed in detail of how to use the system and they should
all have a copy of Appendix A on “Operation and Safety Instructions”.
3.1
Safety
Your Nilfisk-ALTO DELTABOOSTER is designed and made in accordance with the latest rules on safety
at work. In order to prevent injuries to yourself and other persons, the following regulations should always
be observed when operating the plant.
1. WARNING! Never direct the water jet towards people, pets, electric wiring, or
the DELTABOOSTER.
2. WARNING! Never try to clean clothes or footwear on yourself or other per-
sons.
3. We recommend you to wear ear defenders, goggles and protective clothing during operation.
4. Never work barefoot or with sandals.
5. Operator and anyone in immediate vicinity of the site of cleaning should take action to
protect himself from being struck by debris dislodged during operation.
6. Spray handle and lance are affected by a thrust during operation - therefore always hold
the spray handle and lance firmly with both hands.
7. Only activate the trigger by hand. Never tie it up or fix it in any other way.
8. At intervals during operation, the machine should be stopped and the spray handle secured against
inadvertent use by turning safety knob to position O.
9. WARNING! High pressure hoses, nozzles and connections are important for safety when operating
the plant. Only use the high pressure hoses, nozzles and connections prescribed by Nilfisk-ALTO.
10. Avoid damage to the high pressure hose such as running over by a car, squeezing, pulling, knot-
ting/kinking etc. and keep it away from oil and sharp or hot objects, as such may cause the hose to
burst.
11. Never use the water for other purposes than cleaning. Detergents etc. may have been added.
12. Never detach the high pressure hose from an outlet point until the high pressure cock at the outlet
has been properly closed and the high pressure hose relieved of pressure.
13. Only let instructed personnel operate the plant.
14. Never let children operate the plant. Denmark: Persons under the age of 18 must not operate the
plant if the working pressure exceeds 70 bar.
1 5. When using detergents the instructions should always be strictly observed.
16. Persons under the influence of alcohol, drugs and medicine should not operate the machine.
17. Don’t use the machine if important parts of the equipment are damaged - i.e. safety devices, high
pressure hoses, pipeline, spray handle.
Save these instructions for later
The high-pressure pumps of a DELTABOOSTER are fitted with a safety valve each.
The safety valve has been set and sealed from the works.
DO NOT INTERFERE WITH THIS SETTING!
The motors in a DELTABOOSTER are protected against overload as thermal circuit breakers have been
incorporated in the stator windings, and the motor is guarded.
If the motor is subjected to an overload the thermal switches will cut off the system so it stops. After such
a stop the DELTABOOSTER can be restarted without interfering in the electrical system as the failing
motor will automatically be disconnected. After cooling or re-connection of the motor protection, the pre-
viously disconnected motor can be taken into operation again when re-starting the plant as described in
section 3.4.2.
The motor protection disconnects the system if the motor consumes too much power.
Frost protection
The system should be installed in frost-free premises. Pipelines and outlet stations should also be in a
frost-free location.When outlet stations are situated outdoors remember to provide for the cutting off and
draining of that part of the line which is exposed to frost.
If the temperature of the inlet water is above 80°C or below 2°C the plant will be disconnected.

3.4.1 Main / emergency switch
The main switch (1) connects the DELTABOOSTER to the supply network when the switch is
turned from pos. 0 to pos. I. At pos. 0 there is no connection between the DELTABOOSTER and
the supply network and the capacity of the switch is sufficient to use it as an emergency device.
The main switch may be locked in 0 position by means of an ordinary padlock.The switch should
always be locked during service checks of the system.
PLEASE NOTE: The switchboard can only be opened by means of a key and only when the
main switch (1) is in pos. 0.
3.4.2 Control switch / starting switch and stopping switch
The control switch (2) supplies 24VAC control voltage to the DELTABOOSTER when turned to
position I (provided the main switch is in pos. I).
The plant is started up by pressing the starting switch (3).
The plant will now be in operation / stand-by mode until the operation switch is turned back to
pos. 0.
Stop of plants in operation should always be effected on the operation switch and thus only use
the main / emergency switch for power cut off and emergencies.

3.4.3 The control panel
The control panel (5) is based upon a schematic drawing of the system where a number of
control lamps will show the status of the system and possible faults.
The control lamps have been divided into three categories:
Green indicating a coupled unit (valve, C3K)
Yellow indicating an activated sensor (pressure switch, flow, level)
Red indicating a serious fault (leakage, over heating, etc.)
In normal conditions only the green and the yellow control lamps will glow.
If a serious fault arises the relevant red control lamp will start flashing and at the same time the
system will stop operating completely. Status from the other lamps is retained so the condition
at the moment of the fault is visible.
If a red control lamp flashes the system can usually not be re-started until the fault has been
corrected unless a motor pump unit is disengaged because of a too high temperature or a too
high power consumption. The plant can be restarted by following the procedure described in
section 3.4.2 as the steering will disconnect the defective motor. Thus the actual control lamp
will glow contantly (cf. the section on “3.10 Trouble-shooting and correction”).
The meaning of the control panel and the individual control lamps appears from Fig. 2 below.

and may either be put in the OFF position (click function - vertically) or set on the desired
mixing temperature. The yellow diode below the control knob indicates the starting point of the
temperature adjustment.
OFF
In this position the system will allow the parallel inlet of water from the two water connections
into the water tank. This is an advatage if the pressure of the inlet water is low and you can do
without the function of temperature regulation.
No adjustment of temperature is provided for, but the water temperature at the two connections
may be selected freely (lower than 75°C).
The yellow indicator symbol
on the control panel (section 3.6, Fig. 5, symbol 4) is not lit.
ON
50°C
In this position water from the two connections will be mixed to the desired mixing temperature
(e.g. 50°C).
The yellow indicator symbol
on the control panel (section 3.6, Fig. 5, symbol 4) will glow
constantly as an indication that the temperature adjustment has been activated.
The indicator lamp may start to flash while the system is in operation.This means that the tem-
perature adjustment has been cancelled by the controls. This will happen if the water supply
from either the cold or the hot connection is so sparse (closed tap, low water pressure) that the
system is about to enter to a fault situation: “Lack of water”.
Both connections will then be opened in parallel until a high water level has been achieved.The
attempt at mixing to the desired temperature will then be repeated.
The indicator lamp will continue to flash even though the water supply returns to OK and the
temperature adjustment is repeated.
Please note: The flashing can only be removed by restarting the system.

3.5.3 Reading of hour meters
On the hour meters you can read for how many hours each of the motor pump units has been
running. Reading as follows:
Motor pump unit 1
Hours 1/100 hours
Example: 4 hours + 50/100 hour = 4½ hours

3.6 Starting up/running in (cf. Fig. 4)
Once the desired settings have been made the cover of the switchboard should be closed and
both locks activated.
Make sure the water supply has been connected.
Turn the main switch (1) to position I.
Turn the control switch (2), to position I and keep an eye on the control panel (3) to make sure
that water is drawn in and the relief valve closed.
(Are there any red indicator lamps flashing on the control panel? cf. sect. "3.10Trouble-shoot-
ing and corrections")
Press the starting switch (4) and 1 pump will then start running if the line pressure is on working
pressure or even higher. If the pressure is lower, 2 pumps will start and an additional pump will
start every other second until a working pressure has been achieved.

The system is now in operation and water may be drawn off under high pressure at the individual
outlets. If consumption exceeds the capacity of the pumps connected a pump will immediately
be started up and an additional pump will follow every other second until capacity meets con-
sumption.
If consumption drops at the outlets so that the pump capacity becomes excessive, one pump
will stop every 15 seconds, until capacity meets consumption.
The controls determine a rotation between the individual C3K pumps so that all units -time-wise-
are subjected to the same load.
If consumption at the outlets is cut off completely all pumps will stop 1 every 15 seconds. The
system will then be on STAND BY with a working pressure on the line and one or more pumps
will start operating again as soon as the pressure in the line drops below 25 bar or if the outlets
are re-activated.

The operation of the system may be controlled on the control panel.
(cf. sect. 3.4.4, Fig. 2)
From the above figure it appears which pumps and water supplies have been connected at the
moment (green), and the status of the pressure, water flow and water level (yellow).
Below is an example of the indications on the control panel in a given situation.
Fig. 5
1 The water level in the water tank is low - water is being
2 filled from the cold connection and
3 from the hot connection.
4 Temperature adjustment is active (set. 50°C)
5 Pumps no. 1, 3, 4 and 5 have been connected
6 Consumption is lower than the capacity from the
connected number of pumps. Water is therefore being
recirculated (the first connected pump will stop after 15 sec.)
7 The line pressure is on working pressure, H (= high pressure)
and consequently also >25 bar, L (= low pressure)

3.7 Multipressure spray lance system
For each line pressure of 120 and 160 bar a kit of nine different spray lances is available, which
have been especially developed for the Multipressure spray lance system.Each of the nine spray
lances represents a combination of pressure and water volume. Users may therefore always
select the job-right combination of pressure and water volume.
The spray lances for 120 and 160 bar respectively differ in that the spray lances for 120 bar
are fitted with a GREY nozzle protection, and the spray lances for 160 bar are fitted with a
BLACK nozzle protection.
The nine spray lances are marked with each their colour and on the spray lance chart on the
DELTABOOSTER pressure, water volume and number of pumps may be read for the nine types
of spray lance.
The different water volumes and pressures depend on which high-pressure nozzle and which
pre-nozzle the spray lance is fitted with.
For further details on reactive power and nozzle sizes please refer to the Product Description
in sect. 1.9.
Alternative nozzles or spray lances should only be fitted in consultation with your Nilfisk-ALTO
specialists.

lie between 4 and 14). Acids and lyes should not be used undiluted.
The supplier’s instructions and guidelines should be followed very closely, this also applies to
rules on protective garments and drainage.
Detergents which have not specifically been specified for use in high- pressure cleaning should
only be used after prior permission from Nilfisk-ALTO and possibly the supplier.
By using Nilfisk-ALTO detergents users are sure to have machinery, accessories and deter-
gents which are compatible and which are a pre- requisite for optimal solutions to the cleaning
tasks.
Nilfisk-ALTO can offer a wide range of effective substances for professional cleaning and disin-
fection.The products are composed of substances which unite effectiveness with environmental
considerations.

3.9 Maintenance
The DELTABOOSTER is designed to ensure a minimum of maintenance. The following points
should however, be observed in order to secure trouble-free operation.
3.9.1 Service intervals/oil change
"Frequencyofsystemservicingisdependentuponseveralfactorsincludingwatertemperatureand
water quality. We, therefore, recommend that you contact your local service agent for advice."
Change the oil in the pump at each service interval.The pump is supplied with zinc-free hydraulic
oil - “KEW Pump Oil 100”. When replenishing use this or an oil specified to
ISO NO. 100
Viscosity index (VI) min 130
Congelation point lower than -30°C
URGENT: PROTECT NATURE
Waste oil and oil sludge should be removed or destroyed in accordance with local rules and
regulations.
3.9.2 Water filter
There are two filters on the water inlets in order to prevent impurities from entering the high-pres-
sure pumps and thus causing damage. The filters should be cleaned regularly. The frequency
depends on the purity of the inlet water, but daily cleaning would often be required.
Cleaning is accomplished by leaving both inlets open and opening the outlet cocks on filters
(14). The inlet water will then flush away impurities from the filters.
3.9.3 Couplings
In order to prevent leakages and destruction of quick-couplings on hoses, spray handle, outlet
points and spray lances it is urgent to clean them regularly and grease with a little oil or fat.
